The working principle of the invention is as follows: after shearing the batch of steel bars into the required size, hoisting the steel bars to a starting bin 1 by using a travelling crane, driving a first chain wheel 7 to rotate positively and negatively by using a motor, driving a first rotating shaft 6 to rotate positively and negatively, driving a plurality of first chains 5 by the first rotating shaft 6 to rotate positively and negatively together, rolling overlapped and disordered steel bars to a natural material hook fixing plate 9, and after preliminary natural material blocking and carding, rolling the steel bars on the starting bin 1 to fall on the first chains 5 on a material distributing bin 2 by using the positive transmission of the motor; the distributing bin 2 also carries out positive and negative rotation by controlling a motor, and carries out secondary carding on the disordered and overlapped reinforcing bars, then the motor positively transmits the reinforcing bars on the distributing bin 2 to roll and drop on a first chain 5 with a feeding bin 3, the feeding bin 3 automatically feeds the straightened reinforcing bars to a step at the lowest part of a step fixing washboard 11 through the positive transmission of the motor,
because the top surface of the ladder fixed washboard 11 is positioned at one side of the material blocking and turning hook 12 and is inclined downwards, the steel bars slide to the ladder fixed washboard 11 and are positioned at one side of the material blocking and turning hook 12, the motor, the speed reducer, the chain and the chain wheel are matched to drive the cam rotating shaft to rotate so as to drive the eccentric wheel 51 below the moving beam 17 to rotate, the eccentric wheel 51 drives the ladder jacking washboard 16 to move upwards, when the ladder jacking washboard 16 moves upwards beyond the height of the ladder fixed washboard 11, the steel bars on the ladder fixed washboard 11 are supported on the ladder jacking washboard 16, because the top surface of the ladder jacking washboard 16 is positioned at one side of the material blocking and turning hook 12 and is inclined downwards, the steel bars slide to the ladder jacking washboard 16 and are positioned at one side of the material blocking and turning hook 12,
when the eccentric wheel 51 drives the step ejection washboard 16 to move downwards, as the steel bars move to one side of the material blocking and turning hooks 12 on the step ejection washboard 16, the steel bars fall on the next step of the step fixing washboard 11 when falling, so that the step lifting of the steel bars on the step fixing washboard 11 is realized, and the third driving mechanism 18 repeatedly drives the step ejection washboard 16 to move up and down, so that the steel bars are all lifted to the top of the step fixing washboard 11;
the second driving mechanism 14 contracts one end of the material blocking and turning hook 12, so that the other end of the material blocking and turning hook 12 extends out of the top of the step fixing washboard 11, reinforcing steel bars are concentrated at the top of the step fixing washboard 11, and the proximity switch is used for counting the number of the reinforcing steel bars to reach the position of the material blocking and turning hook 12; then the second driving mechanism 14 turns over one end of the material blocking and turning hook 12, so that the other end of the material blocking and turning hook 12 descends to the top of the ladder fixed washboard 11, and the reinforcing steel bars concentrated at the top of the ladder fixed washboard 11 fall into the roller shield 24.
The number of the limiting blocks 20 can be changed according to the size of the steel bars, the fourth driving mechanism 19 is telescopic to enable the movable frame 15 to be tightly propped against the limiting blocks 20, so that the distance that the steps corresponding to the step jacking washboard 16 and the step fixing washboard 11 are staggered in the horizontal direction is changed, when the step jacking washboard 16 ascends, the steel bars on the step fixing washboard 11 can be supported on the step jacking washboard 16, the device is suitable for steel bars of various types, and a plurality of steel bars can also ascend simultaneously according to the requirement.
According to the length of the steel bar to be processed, a sixth driving mechanism 28 at a corresponding position is controlled to move the ejector plate 27 into the drum shield 24; after the steel bars fall into the roller shield 24 from the step-fixed washboard 11, the fifth driving mechanism 26 drives the feeding roller 25 to roll, so that the steel bars move along the length direction of the roller shield 24, and after reaching the position of the protruded liftout plate 27, the steel bars are positioned and aligned by the protruded liftout plate 27; the aligned rollers are turned over by the feeding roller 25, are sent to the designated size position by data counting processing, then the sixth driving mechanism 28 below other lifters 27 except the stretched lifters 27 is stretched out simultaneously, the lifters 27 below the steel bars eject the steel bars out of the roller shield 24, and the steel bars roll onto the first material bearing rod 29 and roll to the automatic discharging steel bar bending device along the first material bearing rod 29 because the tops of the lifters 27 are positioned on one side of the first material bearing rod 29 and incline downwards;
before receiving the reinforcing steel bars, the eighth driving mechanism 39 contracts, so that the lower parts of the compacting rib transition material rods 38 extend upwards and towards the first sliding blocks 36; the seventh driving mechanism 37 drives the first sliding block 36 to slide to the end part of the third sliding rail 35, and a gap is reserved between the first sliding block 36 and the compacting rib transition material rod 38; the tenth driving mechanism 48 extends to slide the moving rod 46 and the slide rod 47 in the direction of the second slider 43; the ninth driving mechanism 44 drives the second slider 43 to slide to the end part of the fourth sliding rail 42, and a gap is reserved between the second slider 43 and the sliding rod 47; the spring pushes the insertion rod 50 upwards under the action of the spring force, so that a gap is reserved between the pressing plate 49 and the end part of the third sliding rail 35;
after the steel bars naturally roll along the first material bearing rod 29, the steel bars pass through the arc parts at the upper parts of the arc rods 45 and the compaction rib transition material rods 38 at the same time and then pass through the lower parts of the moving rods 46 and the compaction rib transition material rods 38 at the same time, so that the steel bars transition into the gaps between the first sliding blocks 36 and the compaction rib transition material rods 38 and the gaps between the second sliding blocks 43 and the sliding rods 47, and then the tenth driving mechanism 48 contracts to drive the moving rods 46 and the sliding rods 47 to retract, so that the steel bars are aligned manually;
the seventh driving mechanism 37 drives the first slider 36 to push the reinforcing bar to the side of the supporting bar 34, and at the same time, the ninth driving mechanism 44 drives the second slider 43 to push the reinforcing bar to the side of the forming wheel 32, so that the reinforcing bar is pushed between the upper and lower clamping plates of the forming wheel 32 and between the compacting plate 49 and the third sliding rail 35; the eighth driving mechanism 39 extends out to enable the lower part of the compacting rib transition material rod 38 to move downwards, enable the compacting plate 49 to move downwards to be matched with the third sliding rail 35 to clamp the middle part of the steel bar, and enable the upper clamping plate and the lower clamping plate of the forming wheel 32 to clamp the two sides of the steel bar; finally, the forming wheel 32 starts to bend until the upper and lower clamping plates of the forming wheel 32 loosen the two sides of the steel bar after the steel bar product is formed,
the eighth driving mechanism 39 is contracted to enable the lower part of the compacting rib transition material rod 38 to move upwards, the middle part of the reinforcing steel bar is loosened, and the spring enables the compacting plate 49 to move upwards through elasticity; finally, the steel bar is taken out to finish a working step.
The present invention will be described in further detail with reference to specific examples.
